Soon, no less than twenty or thirty guards gathered around each tower, most of these monks were around the spiritual stage, but the team was led by some condensate stage demon monks holding array plates.

As soon as these Spiritual Guardians appeared, they set up circles around the tower with great skill.

As the condensation stage monks led by him continuously poured mana into the array disk in their hands, the magic circles around the tower were flooded with blue light, and the billowing blue mist diffused out of it, submerging into the blue light shield above the Sea Emperor's Palace, making the already strong protective shield even more dazzling.

The dense guards of the Sea Emperor's Palace, as well as all kinds of prohibitions all over the place, reflect the entire underwater world brilliantly.

Just when the entire Sea Emperor Palace forces were preparing to resist the Terran Alliance army, in the cave at the bottom of the Sea Emperor Palace, it was a different scene.

In the dozens of acres of caves, a thick and pungent blood-colored mist is everywhere at this moment.

Most of the more than 50,000 icicles in the cave have disappeared at this moment, replaced by blood-colored cocoons.

The surface of these blood-colored cocoons is densely covered with blood vessels and pores, and as if breathing, they bulge rhythmically, and each time they bulge, their size and urine will shrink by a few points, and a blood-colored mist will be emitted from the pores.

Endless blood-colored mist emanated from these tens of thousands of cocoons.

Among the remaining icicles, the original corpse was gradually penetrated by the blood-colored lines connected to the icicles, and gradually turned into a blood-colored cocoon.

After the blood cocoon is formed, the icicle where it is located shatters with a "bang".

As time passed, the remaining icicles burst rapidly, and the sound of "bang" and "bang" shattering came and went.

On the stone platform in the center of the cave, the Siren Emperor sat cross-legged, his whole body was shrouded in blood mist, and his figure had become blurred.

The billowing blood-colored mist converged towards the central platform and slowly seeped into his body.

At this time, the Kraken Emperor's face had a hideous expression, as if he was suffering from great pain.

The eight stone pillars around the stone platform emitted bursts of dazzling blood light, and there seemed to be strands of blood flowing rapidly in the spirit patterns on the surface.

In the air above the stone platform, the cyan jade bead was suspended out of thin air, and the gray light on the surface was uncertain, and the dry voice of the Iron Demon Sect's Yannian mantra came from it.

After a puff of incense, the last icicle finally cracked, revealing the blood-colored cocoon that was constantly open with a crisp sound.

At this moment, a gray light flashed on the jade bead, and a gray-black villain appeared, which was the spirit of the Iron Demon Sect Yan.

"The preliminary preparations are almost complete, and now we will start the real Blood Sacrifice Underworld Technique, summon the eight-eyed Immortal Demon, pour all the mana into your body, and help you forcibly break through the realm. I would like to remind you that you should be prepared for the unbearable pain of this procedure. The Iron Demon said with a twinkle in his eyes.

On the stone platform, the Siren Emperor opened his eyes, nodded slightly, and said nothing.

The iron demon's eyes flashed with a strange color, and then he began to chant the incantation again, and the entire stone platform, the eight stone pillars around it, and all the spirit patterns connected to the blood-colored silkworm cocoon suddenly burst into blood.

The next moment, the billowing blood mist that filled the entire cave began to accelerate towards the center of the stone platform, as if it had been summoned by some kind of summons.

Buzzing!

A blood-colored magic circle suddenly lit up under the Siren Emperor, holding his body up and levitating in midair.

The blood mist that had gathered rolled into the circle turned into sticky blood light and melted into the body of the Siren Emperor.

His face was bruised, and there was a crazy look in his eyes, and it was clear that the pain that the Iron Demon was talking about was not false.

However, the Siren Emperor was able to get to this day step by step, and naturally he was far more determined than ordinary people, although his face was distorted, he still maintained his sanity.

Above the stone platform, the iron demon saw this, a look of surprise flashed in his eyes, and with a wave of his small hand, the speed at which the blood mist gathered slowly accelerated.

The Siren Emperor's face was bruised, but his eyes became brighter and brighter.

With the injection of blood mist, a layer of red appeared on his body, and the aura emitted slowly became stronger.

A hint of joy appeared in the Siren Emperor's eyes, overpowering the pain between his eyebrows.

At this moment, in his body, the blood mist turned into a powerful torrent flowing wildly among his limbs and bones, in addition to the enhancement of mana, the meridians and bones in his body also became stronger under the nourishment of the blood mist.

The Siren Emperor took a few deep breaths, and the pain in his body was gradually left behind by him, and the mana in his body worked from fast to slow according to the method of refining the body of the Heavenly Demon.

In the middle of the stone platform, the gray-black villain transformed by the iron fairy spirit looked at the Kraken Emperor below, but the corners of his mouth flashed a strange smile that was not easy to detect, and he said softly:

"The Demon Appears!"

Suddenly, the eight stone pillars around the stone platform burst into blood, and the blood-colored pupils on the stone pillars flashed, and then the eight stone pillars and the stone platform under the body of the Siren Emperor became blurred at the same time.

The stone platform gradually turned into a somewhat hideous and terrifying huge head, with no mouth and nose on it, only two pointed ears, but the original eight stone pillars turned into eight blood-colored eyeballs the size of a zhang, and eight huge blood vessels connected to the huge head below.

At the moment when the skull was formed, the entire cave was suddenly covered by a cold and demonic aura.

"Snort"!

The eight blood-colored eyeballs connected to the hideous skull flashed with light, and each shot out a blood-colored pillar of light.

Eight pillars of blood-colored light converged into the magic circle around the Siren Emperor's body.

The speed of the blood-colored circle suddenly increased several times, and the blood-colored mist in the cave also gathered at an even faster speed, forming a huge blood-colored vortex.

With the firmness of the Kraken Emperor's will, he couldn't help but let out a muffled snort at this moment, and his body, which was originally sitting cross-legged, struggled in the blood-colored array, and let out a low roar of pain from his mouth.

Time passed, and the thick blood mist in the cave gradually thinned.

A series of deafening roars rang out one after another.

However, the more than 50,000 blood-colored silkworm cocoons actually shattered all of a sudden, turned into a stream of blood mist again, and quickly gathered towards the Sea Demon Emperor's location.

The surrounding blood mist had reached the point of being close to liquid, forming a blood-colored ball several zhang in size around the Kraken Emperor, suspended above the huge hideous head.

The gray-black villain transformed by the iron fairy spirit turned into a little more solemn, and as the sound of the spell in his mouth changed, one after another spells fell from his hands.

The blood-colored orb was like a heart, and it contracted violently and beat violently, making a rumbling sound.

With each beat, the blood-colored orb shrank in size and darkened.

After beating like this for nearly a hundred times, the blood-colored ball had turned into a human-sized oval solid silkworm cocoon.

Click!

A crack appeared on the blood-colored cocoon, and then the crack continued to expand, and finally shattered all at once, revealing a naked body, which was none other than the Siren Emperor.

However, at this moment, the Kraken Emperor's body has also undergone some changes.

There was an extra layer of reddish keratin on its hands and feet, the palms of its hands became extremely rough, with a faint blood on them, and sharp nails grew on its five fingers, which looked a little hideous.

Other than that, its face was the same as before, except that it had become a little paler.

The Siren Emperor quickly opened his eyes and looked at his body a little blankly.

Suddenly, there was a flash of blue light in front of him.

But it was the cyan orb that the Iron Demon was living in flew in front of him, and with a flash of gray light, the Iron Demon's humanoid spirit flew out, looking up and down the Siren Emperor's body a few times, and his little face showed a satisfied look.

"Although it was an incomplete blood map sacrifice, overall, it was relatively successful. The Iron Demon said with a smile.

The Siren Emperor glanced at the iron fairy in front of him, slowly stood up, and moved his body, and a blue and red demonic light suddenly flashed from his body.

The strong force overflowed, and the whole cave shook violently.

"Yes, the mana has reached the Great Perfection of the True Dan Realm, and with the help of the power of sacrifice, the ninth level of the Heavenly Demon Refining Body has also been practiced. The Siren Emperor's face also showed a look of satisfaction.

"In that case, give me your body!"

A hideous look appeared on the iron demon's face, and the cyan bead burst into a cyan net, and it quickly went under the cover of the Kraken Emperor.

Unbeknownst to him, as soon as the cyan bead light lit up, the body of the Siren Emperor had already shot out like lightning, and the cyan net was covered in the air.

"I knew you had bad intentions, Zong Yan old monster, do you think I would fall for your tricks?" the Siren Emperor laughed, his body fell a few feet away, and he waved his hand to play a trick.

A crack opened in the black stone platform, and a gray light flashed, and a gray wooden cage shot out, trapping the Iron Demon and the cyan jade bead inside.

"A prison cage made of Om Xiangmu. The iron demon was trapped in the cage for a while, but his face did not show much panic, his eyes looked at the cage a few times, and said lightly.

"Hehe, I can't imagine it, in a barren place like the Canghai Domain, there is also this kind of ancient divine tree that specializes in harming divine souls, and you don't want to come out of it now. The Kraken Emperor said with a wild laugh.

"Really, do you really think this thing can trap this seat?" the Iron Demon looked calm.

"What else do you have, just cast it!"

Seeing the Iron Demon so calm, a trace of uneasiness flashed in the eyes of the Siren Emperor, but after his face became sharp, he immediately waved his hand and played a spell, and the cage was flooded with gray light.

Illuminated by the gray light, the Iron Elf let out a scream of pain.

Seeing this, the Kraken Emperor made up his mind, and with a pinch of one hand, the gray light on the cage slowly weakened a few points. R1152
